Explain the reason why to have to know the spectrum of a communication signal?
Explain the reason why to have to know the spectrum of a communication signal?
Please list all seven reasons why we use eye contact in communication. For each reason please explain.
(a) Sketch the spectrum of the signal r(t). Show the spectrum as a function of f in Hz For the rest of this problem, assume that the signal is sampled at a rate of fs 50 Hz. (b) Sketch the spectrum for the sampled signal rn). Your spectrum should be shown as a function of the normalized frequency over the interval-2π < -+2T. c) Write an equation for the sampled signal [n. (d) Suppose that the signal is reconstructed from...
Match up the structures with the Spectrums, (A-E), explain why you matched the structure with the spectrum (ex: a large broad signal at approximately 3500cm^-1 so you have chosen an alcohol), and give the name of the IUPAC name of the compound. Structures: OH OH Spectrum A: IOD TPANSTANCIU มา 4000 9000 2000 1500 1000 HAVE NUMBER Spectrum B: 1000 3000 2000 Wavenumber (cm-1) Spectrum C: 3000 1000 2000 Wavenumber (cm-1) Spectrum D: 3000 2000 Wavenumber (cm-1) 1000 Spectrum E:...
Answer the following questions: a) Explain what the frequency spectrum of a signal is (remember that the frequency spectrum is two graphs). b) What's FFT? c) What is the analysis in the frequency domain of a signal? What differences exist with respect to time domain d) Generally, what type of signals do we find in nature (continuous or discrete) and what type of signals do computer systems use (continuous or discrete)?
Explain why or why not each compound of C4H8O2 could or could not be represented on the IR spectrum. 5. (16 points) For each compound with formula C,H,O, provide a brief reason why it could or could not match the IR spectrum. Transmitance 4000 3500 3000 2500 1000 2000 Wavenumbers (cm-1) OH 3-hydroxybutan-2-one ethyl acetate 1,3-dioxane 3-hydroxybutanal
for NMR Spectrum looking at a molecule we have to decide with where the protons are in the environment how many signals will show on the NMR Spectrum. I don't understand why they are saying the protons in the pink are going to all show one signal and the protons in red are going to show their own signal. To me the line of symmetry goes down the middle of the compound and they are symmetrical so they all should...
State the formula that relates the spectrum of the sampled signal to the analog signal spectrum
what are three communication skills nurses need to have? Explain how and why to use them.150 words.
Q2 Consider a communication signal x(t) described by the following mathematical expression: x(t)=2 cos(2000) + 4 sin? (2000) – 2+4rec(t)cos(6000mt) Analyse the communication signal x(t) then consider the following: (i) Determine the Fourier transform of the signal x(t). (ii) Plot the double-sided amplitude spectrum of the signal x(t).
1.Explain what you understand by digital media communication and why do organisations need to have a policy or guidelines in place for staff in using this kind of communication method. 2.List the core areas within a health care industry that you would look for identifying and voicing improvements in work practices.
